TOBACCO-RESWEATINMG DEVIGE.

SPECIFICATION forming part of Letters Patent No. 278,029, dated May 22,1883.

Application filed October 18, 1882. ('No model.)

To all whom it may concern:

Be it known that I, BRUNO MARTIN, of East Saginaw, in the county ofSaginaw and State of Michigan, have invented new and useful Improvementsin Tobacco-Resweatin g Devices; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeinghad to the accompanying drawings, which fornra part of thisspecification.

The nature of this invention relates to certain new and usefulimprovements in devices for resweating tobacco, by means of which thedesired result is produced very rapidly, perfectly, and with a minimumof expense..

The invention consists in the peculiar construction, combinations, andoperation of the various parts, by means ofwhich hydrocarbons areemployed for the generation of steam, such hydrocarbons beingb'urned,through-the medium of a vaporizer, with perfect safety, and theprocessiscarriedon,afterbeingcommenced,

in such manner as to require very little attention.

Figure 1 is a perspective view of my com plete device. Fi g. 2 is avertical cross-section of the same. Fig. 3 is longitudinal verticalcentral section of the combined oil and water a reservoir.

In the accompanying drawings, which form a part of this specification,A-represents a closed water-tank, supported upon suitable brackets uponthe side of the sweat-box B, which in turn is supported upon the table0.

D is an oil-tank, which is suspended within the water-tank, so as toallow the water in said tank to surround the oil-tank on all sides. Thewater-tank is filled through. the opening a, and the oil-reservoirthrough the opening I), both openings being provided with screwcaps orother analogous devices for closing them.

E is a gage for indicating the height or quantity of water in thewater-tank, and F is v a similar gage to indicate the condition of theoil-reservoir.

A pipe, G, conveys the water from the tank A to the boilerorsteam-generator L under the table, its flow being controlled by a cock,0.

H is the pipe which conducts the oil to the burner K under the boiler,its [low being controlledby the stop -eock d and graduatingcock 0.

I is a water-jacket iuclosing the tube H at a point near the table, soas to protect it from possibledangerarisingfrom too close proximity tothe heat ot'the flame.

K is a vapor-burner, of any of the known valve, 71., controlled bythefloat lis the top part of the boiler, removable from the bottom part,but forming, when in place, a steam-tight joint, its lower edge reachingbelow the water-line to form a seal. The steam generated in the boileris made to escape through a removable rose, m, situated in the top I ofthe boiler.

Surrounding the boiler on all sides is the galvanized iron shield O,which serves the double purpose of confining the flames from the burnerto the sides of the boiler, and also to protect the wood-work of thetable, and to still more insure the safety ofthe device, the shield hasits lower edge turned upwardly and outwardly, so as to form a trough, n,which may be filled with water through a little tube, 0, leading to itfrom the outside.

Another metal trough, N, is suspended below the shield 0, whose outerside, 1), completely protects the wood-work of the table and reaches upto the under side of the pan M, to which it is riveted or otherwisesecured, an open space being left between the smalltrough n and themetal covering 1), so as to allow the heated air to pass into the spaceq, to which it also finds access through small perforations r at thecrown of the shield O. The annular trough N is filled with water througha branch pipe,,s, from the water-supply pipe, the height of the water inthe trough being indicated on the outside by awater-gage, t. Resting ontop of the pan M, and forming a steam-tight joint therewith, is thesweat-box, B, which is made of two thicknesses of boards, lined on thewhole inside with galvanized iron, which forms a small air-space betweenit and the boards, said air-space being in communication with the outerair through small perforations in the body of the box. 7 The front sideof the box contains a door, through which-the tobacco is introduced in aproper package, resting upon a truck, which is supported upon rails onthe sides of the box, as has been done heretofore. To control the amountof heat in the sweat-box, whiclriis indicated by a thermometer ontheoutside, one or more ventilators, P, are provided in the sides andtop of the box for the admission of air, while a valve, Q, on the topofthe box, provides for the escape of surplus steam. The pan M is slightlyinclined toward the boiler L, so as to collect the water of condensationin the box in a little depres sion or channel, a, which surrounds theboiler, bringing it thereby more within the influence of the heat fromthe burner, and re-evaporating it or allowing it to flow back into theboiler through a proper channel, which may be provided therefor.

The operation of the device will be readily understood from theforegoing description. After the device is once put into operation itwill be seen that but little attention is needed for the continuousworking, the danger from overheating the parts being effectuallyprevented bythe various safety devices described, and as the locationot'the boiler is so near and central to the place where the heat isrequired it is clear that great economy is attained.

What I claim as my invention is I. In combination with theoil-reservoirD, arranged contiguous to the tobacco-holding box, to economize space,and surrounded by the water within the water-tank A, to prevent thegeneration of gas within the oil-reservoir from the heat of the box orarising gases from the burner K, the said burner, box, andsteamgenerator L, as and for the purposes set forth.

2. In combination with the boiler L and pan M, the annular shield 0,having perforations r and trough n and feed-pipes 0, as and for thepurposes set forth.

3. In a tobacco-sweating device in which the steam is generated in aboiler by heat derived from hydrocarbon fuel fed from a tank inelosed bythe water-tank which supplies the boiler, the combination of saidoil-tank D and watertank A, arranged contiguous to the tobaccoholdingbox, the pipe H, water-pipe I, cocks at and e, burner K, and pan M,whereby the oil is protected from the heat which arises from the burner,as set forth.

4. The combination of the pan M and annular trough N, secured thereto,of the branch pipe 8, gage t, and burner K, as and for the purposes setforth.

, 5. The combination, with the box B, provided with an escape-valve, Q,and having a lining of galvanized iron secured to studs to form anair-space connected with the outer air by perforations in the box, ofthe steam-generator L 1, arranged within the box, as set tforth.

6. The combination, with the burner K and boiler L, having the part Isealed below the surface of the contained water, and the rose 1):, ofthe plate M, having annular groove u to receive the water ofcondensation, whereby said water may either flow back into the boilerorbe evaporated, as set forth.

7. The plate M, forming a close bottom for the tobacco-holding device B,and a reservoir to hold the water from which the steam is generated,combined with the open-topped conical portion l and rose m, as setforth, for the purposes set forth.

8. In a device for resweating tobacco, the metal pan M, supporting'thesweat-box B, and provided with a boiler, L, centrally secured thereto,and forming with its top a part of the bottom of the pan, substantiallyas and for the purposes described.

9. In a device for resweating tobacco, the combination of the boiler L,shield O, and pan M, constructed as described, and combined with the boxB for the purpose of utilizing all the heat obtained from thevapor-burner for generating steam in the boiler and rc-evaporating thewater of condensation from the box, substantially as described.

In witness that I claim the foregoing as my invention I have hereuntoset my hand this 24th day of August, 1882.

, BRUNO MARTIN.
